Alkaloids from Narcissus bujei (Amaryllidaceae)

摘要

Eleven alkaloids have been isolated from whole plants of Narcissus bujei (Amaryllidaceae). The alkaloids 11-O-acetylhaemanthamine and bujeine are reported for the first time. The structure and stereochemistry of these new alkaloids have been determined by physical and spectroscopic methods. The X- ray diffraction analysis of O-methyllycorenine hydrochloride has been performed.
